Abstract Introduction We compared simultaneous measurements of blood lactate concentration Lac in the right atrium RA and in the pulmonary artery PA . Our aim was to determine if the mixing of right atrial with coronary venous blood having substantially lower Lac results in detectable decreases in Lac from the RA to the PA. Methods A prospective sequential .
